EYELET.

SJPEGIFICATION forming part of Letters Patent No. 548,558, dated October22, 1895.

Application filed August 10, 1895.

2"0 aZZ whom it may concern:

Be it known that I, ELEAZER KEMPSHALL, of Sharon, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Eyelets, of which the following is a specification.

This invention relates to eyelets which are coated at their outer endswith a plastic pyroxyline composition or its equivalent.

The invention has for its object to provide an improved construction ofeyelet whereby the plastic covering may be readily applied to andsecurely interlocked with the outer portion of the eyelet; and itconsists in the improvements which I will now proceed to describe andclaim.

Of the accompanying drawings, forming a part of thisspecification,Figure 1 represents a perspective view of an eyeletembodying my invention. Fig. 2 represents a sectional view of the same.Fig. 3 represents a sectional view showing the plastic covering appliedto the flange or outer end of the eyelet. Fig. 4 represents a sectionalview showing a somewhat different form of eyelet.

The same letters of reference indicate thesame parts in all the figures.

in carrying out my invention I construct an eyelet having a tubularportion or barrel a, an on twardly-inclined or frusto-conical flange aat one end of the eyelet, said flange joining the body of the eyelet atan obtuse angle 0. and spurs a formed on the upper or outer edge of theflange a and bent downwardly from said flange, so that their lower endsare substantially on a level with the angle a fdrmed by the intersectionof the body a and flange a of the eyelet.

The eyelet above described is placed upon a die-plate having a cavityformed to receive the barrel or body a and fit closely the exterior ofthe same. The lower portion of the flange is caused by the angle atwhich it joins the body of the flange to rest squarely upon thedie-plate, so that the downward pressure applied, as hereinafterdescribed, to the flange in the operation of applying the head theretowill not crowd or wedge the flange into the cavity of the die-plate. Thespurs a being on a level with the angle a bear upon the upper surface ofthe die-plate and support Serial No, 558,810 (No model.)

the upper edge of the flange during the covering operation, said spurspreventing the flange from yielding downwardly and becoming flattenedagainst the die-plate. The spurs are preferably separated by intervalsof considerable length, as shown in Fig. 1, so that portions of the edgeof the flange are presented between the spurs as cutting-edges, whichreadily cut into the mass of covering material which is presseddownwardly upon the flange,

The covering material is preferably cutout in the form of an annularblank and is placed upon the upper edge of the flange and presseddownwardly thereupon by means of a suitable die formed to enter the bodyof the eyelet and tomold the plastic material into an annularcovering 1) of substantially the form shown in Fig. 3. The raisedcutting-edge of the flange, supported as described by the spurs apartially divides the mass of covering material, causing the outerportion of said mass to flow downwardly and inwardly and cover the outersurface of the flange, the spaces between the spurs enabling thecovering material to readily find its way to all parts of the outersurface of the flange, the said material entering the spaces behind thespurs, so that the covering is interlocked with the flange not only bythe overhang of the flange, but by the engagement of the covering withthe spurs.

In Fig. ll show a shoulder 0. formed at the junction of the flange withthe body of the eyelet, said shoulder being the equivalent of the anglea and aifording more extended support for the flange than said angle.

I claim- 1. An eyelet comprising a tubular body, a frusto-conical flangeformed on one end of said body and inclined outwardly and upwardlytherefrom, and a series of spurs projecting downwardly from the outerand upper edge of said flange, as set forth.

2. An eyelet comprising a tubular body, a frusto-conical flange formedon one end of said body and inclined outwardly and upwardly therefrom, aseries of'spnrs projecting downwardly from the outer and upper edge ofsaid flange, and a covering of plastic material molded upon said flange,said covering being applied to both the outer and inner sides of theflange and interlocked with the spurs;

thereof.

3. An eyelet comprisinga tubular body, and a frusto-conical flangeformed on one end of the body and inclined upwardly and outwardlytherefrom, said flange having supports at its lower and upper edgesadapted to bear upon a die-plate, as set forth.
